Applied, thanks Eric.

This patch points out a potential compat layer problem which sh64.  It
defines the SIOCGSTAMP (and not SIOCGSTAMPNS) ioctls as not constants,
but rather constant values that depend upon the size of the structure
passed in.

But the compat bridges for these timestamp ioctls simply match on the
native ioctl value and then pass it in unchanged to the real handler.
That won't work for sh64 compat layer for 32-bit sh applications.

That's what they get for being different :-)
